Fabales is a cosmopolitan angiosperm order
which consists of four families, Leguminosae (Fabaceae), Polygalaceae,
Surianaceae and Quillajaceae. The monophyly of the order is supported strongly
by several studies, although interfamilial relationships are still poorly
resolved and vary between studies; a
situation common in higher level phylogenetic studies of ancient, rapid
radiations. In this study, we carried out simulation analyses with previously
published matK and rbcL
regions. The results of our simulation analyses have shown that Fabales
phylogeny can be solved and the 5,000 bp fast-evolving data type may be
sufficient to resolve the Fabales phylogeny question. In our simulation
analyses, while support increased as the sequence length did (up until a
certain point), resolution showed mixed results. Interestingly, the accuracy of
the phylogenetic trees did not improve with the increase in sequence length.
Therefore, this study sounds a note of caution, with
respect to interpreting the results of the “more data” approach, because the
results have shown that large datasets can easily support an arbitrary
root of Fabales.
